has anyone experienced the wipers quitting while in use or just not working on extreme cold days?
I'm wondering if this is a motor issue or the linkage.

 

I had a 2016 that the wipers would come on without me turning them on. I ended up fixing it by having the turn signal stalk replaced. Drove me nuts.

 

Mine recently stopped as I was adjusting the speed. They would only work on high, any other speed, intermittent would cause them to stop immediately in any position.

I pulled over, shut it down and restarted and it went back to normal.
